INSTALLATION INSTRUCTIONS

SERIES NS4 FOUR WIRE APPLIANCES

(WALL MOUNT VERSIONS)

Use this product according to this instruction manual. Please keep this instruction manual for future reference.

GENERAL:

Wheelock’s Series NS4 Horn Strobe Appliances are designed to provide independent operation for the horn appliance, when the

strobe circuit is powered. They are the ideal choice for retrofit applications as well as new installations. The NS4 Appliances are UL

Listed under Standard 1971 for Signaling Devices for the Hearing Impaired and UL Standard 464 for Audible Signal Appliances. The

1575W candela wall mounted strobes are listed at 15 candela under UL Standard 1971 and meet 75 candela intensity on axis with low

current draw. They are listed for indoor use only

and equipped with a NS Mounting Plate (NSMP) that can be mounted to single-

gang, double-gang, 4” backbox, 100mm European backbox or SHBB surface backbox (See Mounting Options). These appliances are

Listed for wall mounting only

. The NS4 Appliances use a Xenon flashtube with solid state circuitry enclosed in a rugged Lexan

lens to provide maximum visibility and reliability for effective visible signaling.

The horn portion of the NS4 Appliances can be field set to provide either Continuous Horn or Code 3 Horn. The sound output can be

field set for High (HI) or Low (LO) dBA.

The NS4 Horn Strobe can also be used with a Sync Module (SM) or Dual Sync Module (DSM) to provide synchronized strobe and

synchronized Code 3 signal.

These strobe models are designed for use with either filtered DC (VDC) or unfiltered Full-Wave-Rectified (VRMS) input voltage.

All inputs are polarized for compatibility with standard reverse polarity supervision of circuit wiring by a FACP.

WARNING: NS4 AUDIBLE APPLIANCES SET ON LOW dBA DO NOT MEET THE 75dBA MINIMUM UL

REVERBERANT SOUND LEVEL REQUIRED FOR PUBLIC MODE FIRE PROTECTION SERVICE (NOTED BY * IN

TABLE 1). THIS SETTING IS ACCEPTABLE ONLY FOR GENERAL SIGNALING (NON-FIRE ALARM) USE. USE

THE “HIGH” dBA SETTING WITH THIS TONE FOR PUBLIC MODE SERVICE.

NOTES:

1. Strobes will produce 1 flash per second over the listed voltage range.

2. Anechoic dBA is measured on axis in a non-reflective (free field) test room using fast meter response. For peak dBA (measured

with peak meter response), add 5dBA to anechoic values as shown in Table 2. Reverberant dBA is a minimum UL rating based

on sound pressure measurements in a reverberant test room.

3. All models are UL Listed for indoor use with a temperature range of +32

F to +120

F (0

C to +49

C) and maximum humidity of

85% RH.

Check the minimum and maximum output of the power supply and standby battery and subtract the voltage drop from the circuit

wiring resistance to determine the applied voltage to the signaling appliance.

WARNING: ALTHOUGH UL TESTING HAS VERIFIED THAT THESE PRODUCTS FUNCTION EVEN AT 80% OF

THEIR MINIMUM RATING AND 110% OF THEIR MAXIMUM RATING, WHEELOCK STRONGLY RECOMMENDS

THAT THE VOLTAGE APPLIED TO THESE PRODUCTS BE WITHIN THEIR RATED VOLTAGE RANGE. THE

APPLICATION OF IMPROPER VOLTAGE MAY RESULT IN DEGRADED OPERATION OR DAMAGE TO THESE

WARNING: MAKE SURE THAT THE TOTAL AVERAGE CURRENT, TOTAL PEAK CURRENT AND TOTAL

INRUSH CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE SYSTEM’S PRIMARY

AND SECONDARY POWER SOURCES, SIGNALING CIRCUITS, SM AND DSM SYNC MODULES DO NOT EXCEED

THE POWER SOURCES’ RATED CAPACITY OR THE CURRENT RATINGS OF ANY FUSES ON THE CIRCUITS TO

WHICH THESE APPLIANCES ARE WIRED. OVERLOADING POWER SOURCES OR EXCEEDING FUSE RATINGS

COULD RESULT IN LOSS OF POWER AND FAILURE TO ALERT OCCUPANTS DURING AN EMERGENCY, WHICH

COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

When calculating the total average, peak and inrush currents: Use Table 3 and 3A to determine the highest value of “Rated Average

Current” for an individual strobe (across the expected operating voltage range of the strobe), and use Table 3 to determine the highest

value of “Rated Inrush Current” or “Rated Peak Current” (whichever is higher) of an individual strobe (across the expected voltage

range of the strobe), then multiply these values by the total number of strobes; be sure to add the currents for any other appliances,

including audible signaling appliances, powered by the same source and include any required safety factors.

If the inrush current or peak current exceeds the power supplies’ inrush capacity, the output voltage provided by the power supplies

may drop below the listed voltage range of the appliances connected to the supply and the voltage may not recover in some types of

power supplies. For example, an auxiliary power supply that lacks filtering at its output stage (either via lack of capacitance and/or

lack of battery backup across the output) may exhibit this characteristic.

CAUTION: Series NS4 are not designed to be used on coded systems in which the applied voltage is cycled on and off.

MOUNTING OPTIONS:

CAUTION: The following figures show the maximum number of field wires (conductors) that can enter the backbox used with

each mounting option. If these limits are exceeded, there may be insufficient space in the backbox to accommodate the field wires

and stresses from the wires could damage the product.

Although the limits shown for each mounting option comply with the National Electrical Code (NEC), Wheelock recommends use of

the largest backbox option shown and the use of approved stranded field wires, whenever possible, to provide additional wiring room

for easy installation and minimum stress on the product from wiring.

MOUNTING PROCEDURES:

CAUTION: Check that the installed product will have sufficient clearance and wiring

room prior to installing backboxes and conduit, especially if sheathed multiconductor

cable or 3/4" conduit fittings are used.

1. NS4 models have an integrated NS Mounting Plate (NSMP).

2. The NS Mounting Plate (NSMP) must be oriented correctly when it is mounted to the

backbox. Turn the NSMP so that the arrow below the word ‘‘Top’’ points to the top

side of the NSMP.

3 . NS4 models can be flush mounted to a standard single-gang backbox (Figure A), 4” or

100mm backbox (Figure B) or double-gang backbox (Figure C). NS4 models can also be

surface mounted to a 4’’ or 100mm backbox (Figure B), double-gang backbox (Figure C)

or the SHBB (Figure D).

4. Mount the NSMP first to the backbox. Next slide the Beauty Plate over the NSMP

until the 2 side snaps of the NS Beauty Plate engage with the NSMP.

5. The NS Beauty Plate can be removed from the strobe assembly once engaged. First,

gently insert a screwdriver into one of the slots located on the side edges of the NS

Beauty Plate. Second, gently pull away from the wall with the inserted screwdriver to

disengage the snap. Third, repeat the first and second steps for the second slot.

Finally, gently lift the Beauty Plate away from the NSMP.

6. Mounting hardware for each mounting option is supplied.

7. Conduit entrances to the backbox should be selected to provide sufficient wiring

clearance for the installed product.

8. When terminating field wires, do not use more lead length than required. Excess

lead length could result in insufficient wiring space for the signaling appliance.

9. Use care and proper techniques to position the field wires in the backbox so that

they use minimum space and produce minimum stress on the product. This is especially

important for stiff, heavy gauge wires and wires with thick insulation or sheathing.

10. Do not pass additional wires (used for other than the signaling appliances) through

the backbox. Such additional wires could result in insufficient wiring space for the

signaling appliance.

CAUTION: If these appliances are operated within 15 inches of a person's ear, they can produce a sound pressure level that

exceeds the maximum 120dBA permitted by ADA and OSHA rules. Exposure to such sound levels can result in damage to a person's

hearing.

NS4-24110W strobe models are Listed for use in sleeping or non-sleeping areas when installed in accordance with appropriate NFPA

Standards and the Authority Having Jurisdiction.

WARNING: INSTALLATION OF WHEELOCK 110 CANDELA STROBE PRODUCTS IN SLEEPING AREAS

SHOULD BE WALL MOUNTED AT LEAST 24" BELOW THE CEILING AS FOLLOWS: (1) THE ON AXIS

(DIRECTLY IN FRONT OF LENS) LIGHT OUTPUT SHOULD BE DIRECTED AT THE EYE-LIDS OF THE SLEEPING

PERSON, E.G. PILLOW END OF BED, BED HEAD; (2) NO PART OF THE BED SHALL BE MORE THAN SIXTEEN

(16) FEET FROM THE STROBE NOTIFICATION APPLIANCE. INSTALLERS MUST ADVISE OWNERS AND

OPERATORS OF BUILDINGS WITH SLEEPING OCCUPANTS, E.G. HOTELS AND MOTELS, TO WARN GUESTS,

RESIDENTS AND EMPLOYEES TO NOT MOVE THE BED LOCATION TO A POSITION VIOLATING POINTS (1)

AND (2) ABOVE OR SERIOUS INJURY AND/OR LOSS OF LIFE MAY OCCUR DURING A FIRE EMERGENCY.

WARNING: A SMALL POSSIBILITY EXISTS THAT THE USE OF MULTIPLE STROBES WITHIN A PERSON'S

FIELD OF VIEW, UNDER CERTAIN CIRCUMSTANCES, MIGHT INDUCE A PHOTO-SENSITIVE RESPONSE IN

PERSONS WITH EPILEPSY. STROBE REFLECTIONS IN A GLASS OR MIRRORED SURFACE MIGHT ALSO

INDUCE SUCH A RESPONSE. TO MINIMIZE THIS POSSIBLE HAZARD, WHEELOCK STRONGLY RECOMMENDS

THAT THE STROBES INSTALLED SHOULD NOT PRESENT A COMPOSITE FLASH RATE IN THE FIELD OF VIEW

WHICH EXCEEDS FIVE (5) Hz AT THE OPERATING VOLTAGE OF THE STROBES. WHEELOCK ALSO

STRONGLY RECOMMENDS THAT THE INTENSITY AND COMPOSITE FLASH RATE OF INSTALLED STROBES

COMPLY WITH LEVELS ESTABLISHED BY APPLICABLE LAWS, STANDARDS, REGULATIONS, CODES AND

GUIDELINES.

NOTE: NFPA 72/ANSI 117.1 conform to ADAAG Equivalent Facilitation Guidelines in using fewer, higher intensity strobes within

the same protected area.

CAUTION: Check the installation instructions of the manufacturers of other equipment used in the system for any guidelines or

restrictions on wiring and/or locating Notification Appliance Circuits (NAC) and notification appliances. Some system

communication circuits and/or audio circuits, for example, may require special precautions to assure electrical noise immunity (e.g.

audio crosstalk).

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital appliance, pursuant to Part 15 of the

FCC Rules. These limits are designed to provide reasonable protection against harmful interference in residential installation. This

equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions,
